TO ALL'WHOM IT MAY CONOERN:

Be it known that I, STEPHEN CHAMBERLIN, of Boston, in the county of Suii'olk, and State of Massachusetts, have invented an improved Tip-Wagon; andl do hereby declare that the following, takenin connectionwith the drawings which accompany und form p art of this specification, is a 'description of my invention sufficient to enable those skilledin the art to practise it. i l

The invention relates `to the construction of four-wheelA wagons with relation to a -provision for tipping or dumping. Such provision as applied to a four-wheel wagon is notirl-itself new, my invention consisting in my peculiar construction for eiecting the purpose; that'is to' say, my improvement consists prixnarily inA supporting the body over the rear axle-tree upon springs running lengthwise of the wagon,'when Asuch springs are fixed to the body, and are so mounted as to have a capability of rocking movement upon the axleltree, as will be herein explained.

The drawings represent a wagon embodying my improvement, A showing a'reverso'plan, B a side elevation,

^ and C a rear elevation 'of the saine;

a denotes the wagon body, b the front, and c the rear axle, supported respectively fon thefront and rearv wheels d e. The rear axle-tree bedfis connected to the front transom-bar 'g by the perch h, and the body is so hung that its front partition boardz' comes directly 'over thetransom-bar g' and axleb, while the rear axle comes alittle more than halfway back to the rear board k. The body lsdireotly supported on threesprings, the front one of which,-l, running transversely across the wagon, is vpermanenti'yiastened to the transom g,`and has the wagon restin'g'looselyupor its opposite ends, and so asrto tip up therefron1,-when necessary, metal bearingplates m being fixed to thewagou for the said ends to play upon, while the othertwo springs un run lengthwise of the wagon, and have their ends secured to the body a by bolts o andloops o', which permit the springs to expand lengthwise as the wagon body-settles down upon'thenn, but confine th body to the springs and truck.

Fixed to theunder side of .each spring n at its centre is a plate, p, havingvertical ears or projectionsgq, carry ing a crossebolt or journal, 11, which restsin a socket-bearing or bed, x, von top of the axle-tree bed f, to which, and the axle, thissocket-bearing is confined by suitable straps and screw-nuts t, the strap passing over each bolt g, but allowing it to rock -freely there. The springs un, and with them the body thereto attached, rock freelyupon the rear axle-tree by means of these journals and their socket-bearings, while the body is prevented from any twisting movement relatively to the'rear aile, as will be readily under stood. The wagon-body is fastened down upon the front spring l byu. chain, and an oye-bolt and hook, or by any other suitable locking o r conning device, and in this position the wagon body-is prepared for carrying'any and all such materials as are transported either in cominou dumping-carts or in four-wheel wagons, while by loosening the chainthe body may be'readily tipped up on the rear axle, as shown by the red lines'at B, to empty the contents thereof. V

The vwagon is designed particularly as a substitute for the ordinary two-wheel coal-carts, and combines with the advantages of a four-wheel spring-wagon, that which all dump-carts-havc,- of being emptied'of their contents by simply removing the back board and tipping-the body on the'axle. To support the seat a I-extend the side boards vv of the wagon body out beyond the axle-tree and beyond the front partition board z', as seen by dotted lines at B, and fasten the seat directly upon the top edges of theside and front boards, 'projecting the-foot' 4board out to correspond. l j

I claim the combination and arrangement of the body a, rocker-springs n, journals 1', and socket-bearings s, together and relativelyto the spring l and front and rear axles, substantially as described.

STEPHEN OHAMBERLIN.
